“The following project will describe how to turn 5 discrete components into a building block which when serially connected will form an extendable flashing lighting chain.
Just a simple discrete solution without the aid of a microcontroller. Even so each block can have a different coloured LED and these can be assembled within the chain in any colour combination required.
Not a replacement for a Neopixel just different.
Supplies:
Point LED red_
_BC849 SOT23
equivalent components may be substituted.
_47K 1206
470R 1206
10uF/16V Electrolytic
21 AWG solid core Enamelled copper wire or flexible wire.
Eagle PCB software
FlatCAM
Candle GRBL
3018Pro or similar
Single sided copper clad PCB board
Alternative Assembly - Stripboard
_NPN Transistor (ZTX337)
3mm Low Current LED
equivalent components may be substituted.
47K resistor
470R resistor
10uF/16V Electrolytic capacitor
One set of components per block is required. Just multiply the component (5) by the number of blocks.
Stripboard.”
